Lamborghini unveiled the Countach 5000 Quattrovalvole, the most powerful version of the wedge-shaped supercar that had first appeared as a prototype at the 1971 Geneva Motor Show. A few months earlier, Ferrari had introduced the Testarossa, and Lamborghini answered with a new V12 that featured four valves per cylinder, the feature that gave the car its name. In European form, the 5.2-liter engine used six downdraft Weber carburetors and produced 449 hp (455 PS) at 7,000 rpm and 369 lb-ft (500 Nm) of torque at 5,200 rpm. That output exceeded the published figures for both the Testarossa and Ferrari\u2019s limited-production 288 GTO, making the Countach QV one of the most powerful production supercars of its era. Lamborghini built 610 examples between 1985 and 1988.<\/p>\n<h2 dir=\"ltr\">Background and Origins<\/h2>\n<figure id=\"attachment_900224\" aria-describedby=\"caption-attachment-900224\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-900224\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-7-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-900224\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p dir=\"ltr\">Lamborghini spent much of the 1970s in financial trouble. The company entered receivership in 1978 and was placed into liquidation in 1980, before the Mimran family took control and provided the financial backing that allowed development of the Countach to continue. The LP500 S, introduced in 1982, enlarged the V12 to 4,754 cubic centimeters, but by the mid-1980s the Countach faced stronger competition. Ferrari\u2019s Testarossa, unveiled at the Paris Motor Show in October 1984, was a formidable rival, with a 390 hp flat-12, distinctive Pininfarina styling and a more road-focused approach to supercar performance.<\/p>\n<figure id=\"attachment_900225\" aria-describedby=\"caption-attachment-900225\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-900225\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-6-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-900225\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p dir=\"ltr\">Lamborghini responded by substantially revising the Countach\u2019s V12 rather than replacing the car. Under the company\u2019s engineering leadership, which then included former Maserati engineer Giulio Alfieri, the engine gained a longer stroke, a larger displacement and new four-valve cylinder heads. The result was a major increase in power that restored the Countach\u2019s place at the top of the supercar world. The car retained Marcello Gandini\u2019s dramatic design for Bertone, still one of the most recognizable automotive shapes more than a decade after its introduction.<\/p>\n<h2 dir=\"ltr\">Design and Engineering<\/h2>\n<figure id=\"attachment_900228\" aria-describedby=\"caption-attachment-900228\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-900228\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-1-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-900228\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p dir=\"ltr\">The Quattrovalvole\u2019s V12 kept its 85.5-millimeter bore, while a longer 75-millimeter stroke increased displacement to 5,167 cubic centimeters. It used double overhead camshafts per bank, four valves per cylinder and a 9.5:1 compression ratio in European form. The biggest change for European cars was the move from the 5000 S\u2019s sidedraft Weber carburetors to six twin-barrel Weber 44 DCNF downdraft carburetors mounted on top of the engine. This setup produced 449 hp at 7,000 rpm and 369 lb-ft at 5,200 rpm. US-market cars instead used Bosch K-Jetronic mechanical fuel injection to meet emissions regulations, producing a published 420 hp, and they were fitted with impact-absorbing bumpers to satisfy American safety rules.<\/p>\n<figure id=\"attachment_900227\" aria-describedby=\"caption-attachment-900227\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-900227\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-3-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-900227\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p dir=\"ltr\">The Countach kept its distinctive drivetrain layout. The V12 was mounted longitudinally behind the cabin, with the five-speed manual gearbox positioned ahead of the engine between the seats and drive returning to a rear differential. This arrangement concentrated the main masses near the center of the car. The chassis was a tubular steel space frame, while the bodywork was mainly aluminum, with fiberglass used for some add-on parts. The new engine cover was made of Kevlar composite, and later cars also received a composite front lid. The suspension used double wishbones with coil springs at all four corners, and the brakes were ventilated discs. Published performance figures put 0-60 mph acceleration at about five seconds.<\/p>\n<h2 dir=\"ltr\">Styling<\/h2>\n<figure id=\"attachment_900226\" aria-describedby=\"caption-attachment-900226\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-900226\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-10-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-900226\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p dir=\"ltr\">The Quattrovalvole looked much like the 5000 S, retaining the wheel-arch extensions, front air dam and wide rear tires added to the Countach in earlier updates. The clearest change was at the rear. On European cars, the downdraft carburetors required a large bulge in the engine cover, which further reduced the already limited rearward visibility. US-market cars had a different engine cover with two smaller raised sections for the fuel-injection system. The large rear wing remained a popular and expensive option. It added drag and reduced top speed, while doing little to improve the car\u2019s overall aerodynamic performance. In 1987, Lamborghini added body-colored side skirts with integrated rear brake cooling vents, giving later QVs a visual distinction from early cars with smooth sills.<\/p>\n<h2 dir=\"ltr\">Interior<\/h2>\n<figure id=\"attachment_900229\" aria-describedby=\"caption-attachment-900229\" style=\"width: 1920px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-900229\" src=\"http:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4.webp\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4.webp 1920w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-300x169.webp 300w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-1024x576.webp 1024w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-100x56.webp 100w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-770x433.webp 770w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-1536x864.webp 1536w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-500x281.webp 500w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-293x165.webp 293w, https:\/\/www.supercars.net\/blog\/wp-content\/uploads\/2026\/10\/1985-lamborghini-countach-5000-qv-4-1400x788.webp 1400w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><figcaption id=\"caption-attachment-900229\" class=\"wp-caption-text\">Credit: Broad Arrow Auctions<\/figcaption><\/figure>\n<p dir=\"ltr\">The cabin remained tight, especially for taller drivers, and rear visibility was poor. The scissor doors, low seating position and wide sills required a particular technique to get in and out of the car.

During that period, in April 1987, Chrysler acquired Lamborghini from the Mimran family in a deal widely reported at about $25 million. The QV was succeeded by the Countach 25th Anniversary, introduced in 1988 with styling revisions by Horacio Pagani as the model\u2019s final evolution. Countach production ended in 1990, when the Diablo took over as Lamborghini\u2019s flagship.<\/p>\n<p dir=\"ltr\">The Quattrovalvole represented the Countach at its most powerful. It put the car back at the top of the supercar performance tables against a new generation of Ferrari rivals, while keeping the outrageous design that had made the Countach a symbol of the 1970s and 1980s.
